BACKGROUND: Hemophagocytic syndrome (HPS) is a rare clinicopathological condition characterized by the activation of macrophages with prominent hemophagocytosis in bone marrow and other reticulo-endothelial systems. HPS can be familial or secondary to infections including viruses. AIM: To study the viral markers in patients with HPS. MATERIALS AND METHODS: Serum samples of patients with HPS and control group were screened for anti EBV VCA IgM, and IgG, anti-Parvo B19 IgM, and anti-CMV IgM antibodies using commercially available ELISA kits and CMV and ParvoB19 DNA by polymerase chain reaction (PCR)...

Red Baby Syndrome is a new disease seen in infants and young children. Dramatic onset of clinical symptoms with high intensity, short duration and lack of similarity with other cutaneous lesions makes it distinct. Of 50 such patients studied over a period of 5 years, half were below one year of age. Abrupt onset of high fever and generalized erythema involving the entire skin, which is swollen and tender is characteristic. These children were highly irritable and had paradoxical cry when cuddled. Rapid resolution of symptoms occurred in 7-10 days with extensive desquamation...

Kikuchi-Fujimoto disease (KFD), also know as histiocytic necrotizing lymphadenitis, is a benign disorder characterized histologically by necrotic foci surrounded by histiocytic aggregates, and with the absence of neutrophils. KFD was recognized in Japan, where it was first described in 1972. The disease is most commonly affecting young women. The cause of the disease is unknown, and its exact pathogenesis has not yet been clarified. Many investigators have postulated viral etiology of KFD, connecting it with Epstein Barr virus, human herpes simplex virus 6 parvo B 19, but also with toxoplasmic infection...

There is broad evidence that enteroviruses and adenoviruses can induce an acute inflammation of the myocardium without cardiac dysfunction (i.e. myocarditis) or with cardiac dysfunction (i.e. inflammatory cardiomyopathy) that can transform to a virus-negative dilated cardiomyopathy. In the adult patient neither other viruses (parvo-B 19 virus, hepatitis C virus, cytomegalovirus) nor post-infection autoimmunity are likely to induce idiopathic dilated cardiomyopathy.

Transfusion transmitted disease (TTD) is a major challenge to the transfusion services all over the world. The problem of TTD is directly proportionate to the prevalence of the infection in the blood donor community. In India, hepatitis B/C, HIV, malaria, syphilis, cytomegalo virus, parvo-virus B-19 and bacterial infections are important causes of concern. Hepatitis B and C infections are prevalent in India and carrier rate is about 1-5% and 1%, respectively. Post transfusion hepatitis B/C is a major problem in India (about 10%) because of low viraemia and mutant strain undetectable by routine ELISA...
